## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_balance",
    "arguments": {}
  }

```

## Why get_balance is rated Low

This tool purely retrieves and queries balance data without side effects. It does not create, modify, delete, or transfer data. Even in a blockchain context where financial assets are involved, reading a balance is a non-destructive query operation. The tool has minimal blast radius as misuse would only expose read access to public blockchain data.

From the tool's own definition: "Tool name is 'get_balance' and description states it 'Check[s] the balance of 0G native tokens for any wallet address' with no mention of modifications, deletions, or state changes. Returns balance information and explorer link only."

## Use case

AI agents call get_balance to retrieve information from 0g Chain without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches 0g Chain:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_balance": {}
  }
}
```
